Submarine Waterproof Masturbator

Description

Submarine: An Automatic Thrusting Masturbator Built for Water

Most automatic male masturbators ask you to stay dry. The OTOUCH Submarine doesn't. It's a fully IPX7-rated waterproof masturbator , engineered to deliver true automatic thrusting along with 360° contraction and vibration — submersible up to 1 meter, so the shower or bath is no longer off-limits.

If you've been searching for an automatic male masturbator that doesn't compromise on power just because it's designed for wet use, this is the category Submarine was built to redefine.

What Makes It a True Automatic Thrusting Masturbator

Submarine doesn't rely on vibration alone to simulate motion. It's a genuine automatic thrusting masturbator , with 5 distinct thrusting modes that generate real, mechanical back-and-forth motion — not just a buzzing sensation marketed as movement. Layer in 360° contraction and 7 vibration modes, and you get three independent functions working together rather than one feature doing all the work.

• 5 automatic thrusting modes — smooth, rhythmic strokes that replicate natural motion
• 360° contraction — manual and automatic, tightening from every direction
• 7 vibration modes — stackable with thrusting and contraction, not a standalone substitute for either

A Waterproof Masturbator You Can Actually Trust in Water

A lot of products marketed as water-friendly are really only splash-resistant. Submarine is a genuinely rated waterproof masturbator : IPX7-certified, tested for full submersion up to 1 meter for 30 continuous minutes. That's not a marketing claim — it's a specific, testable engineering standard, and it's the reason Submarine works equally well in the shower, the bath, or rinsed clean afterward without a second thought.

Being a true waterproof masturbator also means hygiene is simpler. Rinse it under running water after every session, no special handling required.

Why Automatic Matters Here

Plenty of devices labeled automatic male masturbator only automate one function, usually vibration, while leaving stroke motion entirely manual. Submarine automates the thrusting itself, which is the harder engineering problem to solve well. Combined with hands-free 360° contraction, it's designed for genuinely hands-free sessions, not just hands-free vibration.
